Numerical modelling of thermal phenomena in Yb:YAG laser welding process

Abstract: Abstract. This paper concerns numerical modelling of the Yb:YAG laser beam welding process. Numerical algorithms are developed for the analysis of thermal phenomena in a laser welded joint taking into account the motion of the liquid material in the welding pool. The model describing the laser beam heat source power distribution is developed on the basis of the kriging method. The heat source model uses the real laser beam profile obtained from experimental measurements of the beam emitted from a Trumpf D70 la… Show more

“…Two approaches dominate in temperature field modeling of these processes. The first approach is numerical, in which the finite difference methods, infinitesimal heat balances and FEM are commonly used [1][2][3][4][5][6][7]. The second approach consists of an analytical solution, described further in this work, in which integral transformations and the Green's function method are used frequently.…”
